对DC-DC转换器以及集成开关稳压器的EMI问题的探讨

Electromagnetic energy, whether intentionally or unintentionally generated, results in Electromagnetic Interference (EMI) with other equipment. Power Trends’ products are designed to minimize the amount of electromagnetic energy
produced during normal operation. The permissible level of conducted and radiated EMI generated by any end product is regulated by a number of governing bodies throughout the world. Their function is to insure Electromagnetic Compatibility (EMC) of all electronic equipment. To assist designers with compliance in the U.S. and European markets, Power Trends has designed and tested its products to several important standards. The table below shows a comparison of several key standards that define radiated emissions levels.
